IMPROVEMENT lN DI STILLING TURPENTINE FROM WOOD.

Specification forming part of Letters Patent No. 44,435, dated September27, 1864.

, tine; and I do hereby declare the following to be a full and exactdescription of the same.

This invention consists in distilling turpentine directly from yellowpine or other wood in the form of blocks, shavings, sawdust, or anychips made by machinery or otherwise and immersed or thoroughlysaturated with water or steam, whereby the turpentine contained thereinmay be thoroughly extracted without danger of combustion, and by which aconsiderable quantity of this useful article maybe obtained from woodwhich has been depleted as far as possible by the process most commonlyemployed.

In order that others skilled in the art to which my invention appertainsmay be enabled to fully understand and use the same, I will proceed todescribe the manner of carrying it into client.

The blocks, chips, shavings, or sawdust are either steamed or placedwithin the still with a large quantity of water and then thoroughlyboiled. This boiling or steaming process exjuicy matter containingturpentine and. adapts any that may remain in the woody substance itselfafter it has undergone the boiling or steaming operation to be morereadily distilled. After the juicy matter containing the turpentine hasbeen released from the wood by the boiling or steaming process theturpentine may be distilled therefrom in customary manner, a largequantity of water being, by preference, used in the still.

By this process the distiller is enabled to produce a considerablequantity of turpentine from wood which has already been depleted ascompletely as possible by the usual process, and which may have beenthrown aside as altogether useless for the purpose in question.

Having thus described my invention, what I claim as new therein, anddesire secure by Letters Patent, is-

Distilling turpentine directly from wood saturated or thoroughlymoistened with steam or water, substantially as set forth.
